The State Department is warning those planning to travel outside the U.S. to use caution depending on where they’re headed, including for trips to a pair of popular European destinations. Americans looking to visit Italy or the United Kingdom are asked to use “increased caution” when visiting due to the possibility of terrorist attacks.

Earlier this month, the department issued separate “Level 2″ warnings for both Italy and the U.K. that say terrorism is possible in those destinations. In particular, travelers should be more prepared when visiting “transportation hubs, markets/shopping malls, local government facilities, hotels, clubs, restaurants, places of worship, parks, major sporting and cultural events, educational institutions, airports, and other public areas.”

For those headed to the U.K., the State Department also said “there is also a risk of isolated violence by dissident groups in Northern Ireland, focused primarily on police and military targets.”

The travel alerts are issued by the Department of State’s Bureau of Consular Affairs, and range on a scale of 1-4 with Level 4 being the highest risk.

If you do travel to areas where the terrorism risk is considered higher, the State Department says you should have contact information for the embassy in the country and use extra caution when in crowded public areas. You should also follow instructions for the local authorities and know which local news outlets you can follow for information in the event of an attack.

Other travel destinations recently flagged for a Level 2 risk include: Bahrain, Jordan, Saudi Arabia, Sri Lanka and Tanzania. Level 3 warnings — which comes with a “reconsider travel” warning have recently been issued for: Bangladesh, Guyana and Pakistan.

The updated list of travel warnings can be found on the State Department website.
